1) remainder = 4

2) remainder is undefined

Step-by-step explanation:

1) 5²/7


\begin{gathered} =\text{ }(25)/(7) \\ =\text{ 3}(4)/(7) \\ \text{reamainder = 4} \end{gathered}

2) (5^2005)/7


\begin{gathered} =\text{ }(5^(2005))/(7)=\text{ }(\infty)/(7) \\ \text{SInce we can't divide infinity by 7, the remainder is undefined} \end{gathered}
